xauth: Add an authorization for a specific display.

xauth

$ xauth add ${display_name} ${protocol_name} ${key}

try on your machine

The command "xauth add ${display_name} ${protocol_name} ${key}" is used to add authentication credentials for remote X Window System sessions.

Here's what each part of the command represents:

"${display_name}": It refers to the display name of the X server for which the authentication credentials are being added. Typically, this takes the format "hostname:display_number", where "hostname" is the name or IP address of the machine running the X server, and "display_number" is a unique identifier for a specific X display.
"${protocol_name}": It represents the authentication protocol being used. The most common protocol is "MIT-MAGIC-COOKIE-1", which is a simple file-based authentication mechanism. Other protocols like "XDM-AUTHORIZATION-1" can also be used for different purposes.
"${key}": This represents the specific authentication key or cookie associated with the display. The authentication key is a unique value that is used to prove the authenticity and authorization of the remote X client trying to connect to the X server.

When you execute this command, it adds the provided authentication credentials (display name, protocol name, and key) to the X authority file. The X authority file is a file that stores the authentication information required for clients to connect to the X server securely. This way, the X server can verify the authenticity and authorize remote connections from clients with the matching authentication credentials.
